Foot ulceration in diabetes mellitus is common. Foot problems remain the most common cause of hospital admission among patients with diabetes mellitus in developed countries. The lifetime risk of a patient with diabetes developing an ulcer may be as high as 30%, and up to 85% of all lower limb amputations in diabetes are preceded by foot ulcers. Up to 50% of older patients with type 2 diabetes have risk factors for foot problems, and regular screening by careful clinical examination is essential; those found to be at risk should attend more regular follow-up, with education in foot self-care.
